Crash

Music, direction and feel is very similar. So similar that IMO, it opens itself up to a cross over for Taxi Driver season 3.

Really similar probably because the main male is the same. has an investigation by the police and a crime from years ago that resurfaces, was swept under the carpet, and blamed on someone else.

It is also deals with peculiar cases in every episodes and Male lead has some past and he overcomes it by solving the cases . The team environment pretty similar and in First Responders it is much more fun and interesting. If you like crash , go for this .

It depicts the story of the Traffic Crime Investigation Team (TCI), which tracks only car crimes such as insurance fraud, retaliatory driving, self-harm blackmail, leka, call jump, and autonomous driving. Cha Yeon Ho, a rational individualist from KAIST, and Min So Hee, a traffic investigation ace with cool judgment and warm sensitivity, track unusual traffic crime cases with the traffic crime investigation team to uncover the truth behind them.

They're both fun detective dramas. You will literally have so much fun watching either, honestly because both of them have a team and each character has their own personality and they work so well together

The concept is slight similar
- Police working in Traffic Division (Crash - TCI, H&R Squad - Hit & Run also catching a villian)
- Team trying their best to nab the criminals
- Nowadays its trending of remaking dramas from movies I believe this drama might be loosely inspired or adapted from this movie

-Police theme
-Comedy
-Teamwork
-Investigation
-Seoul Busters follows violent crimes whereas Crash is about traffic crimes

Police that work together as a team, mixed with comedy. Both FL kind of similar, but in flexxcop the ML is eccentric and in crash he is the opposite
